havehas

Havehas is a neologism used in linguistics and internet discourse to describe the interaction and confusion between the English auxiliary verbs have and has in tense and aspect constructions. The term combines the two forms to symbolize their overlap in nonstandard or didactic contexts.

Origins and scope: Havehas is not a formal grammatical category. It appears mainly in blog posts, discussion forums, and teaching materials as a lighthearted label for errors that involve selecting the correct auxiliary according to subject agreement and tense, for example in the present perfect or in rapid speech.

Pedagogical use: Teachers may invoke havehas to illustrate why “has” is used with third-person singular subjects (she has, it has) and “have” with I, you, we, they, as in “they have gone” or “she has gone” to show regular patterns and the irregularities when contracting or in advanced forms.

Computational linguistics and corpora: In annotated datasets or parsing experiments, havehas can appear as a placeholder label for tokens involving auxiliary verbs, or as a diagnostic example to test a model’s handling of subject-verb agreement and tense. It has no official status in grammar guides.

See also: have, has, present perfect, subject–verb agreement. References: Not an official term in standard grammar; discussions are typically found in learner grammars, language blogs, and pedagogy materials.
